Note 1.1 Most Bluetooth headphones / speakers can only connect to one device at a time so we recommend that you TURN OFF the Bluetooth function on your mobile phone / tablet if they have previously been paired with your headphone / speaker.
Step 1: Find Bluetooth icon in the taskbar and go to ‘‘Add a Bluetooth device’’. Click “Add Bluetooth or other device” > “Bluetooth”
Step 2: Put your Headphones/Speakers into Bluetooth Pairing Mode.
Headphone / Speaker 1st-Time Use: The Headphone/Speaker should enter pairing mode automatically when powered on.
Note 1.2 : Non-1st-Time Use: Merely powering on WILL NOT get it into pairing mode, you'll need to do so manually. Please either refer to the brand list below or refer to your Headphone/Speaker's user manual. You also can search on Google. E.g. “Bose QC35 Bluetooth Pairing Mode”
Step 3: Select the target Bluetooth device and click to pair & connect.
Once successfully paired, this is what you'll see:
For music streaming & calls, if there is no sound, please go into the sound settings menu of Windows AND the App you're using (Skype, Zoom etc.) and make adjustments. Please check here for details.
